Abstract

We applied the polymerase chain reaction (PCR) method to detect gag, env and pX sequences of human T cell leukemia virus type I (HTLV-I) provirus in peripheral blood lymphocytes of seronegative infants born to HTLV-I seropositive mothers. Out of 22, five subjects were found to contain the HTLV-I provirus genome. Two of the five cases were judged to be negative for not only anti-HTLV-I antibodies but also the viral antigens on cultivated lymphocytes by the conventional antibody/antigen detection methods. These results indicate that PCR is of great use as a simple and highly sensitive method detect HTLV-I infection.

摘要

我们应用聚合酶链反应(PCR)方法检测人类嗜T淋巴细胞病毒I型(HTLV-I)血清反应阴性婴儿外周血淋巴细胞中HTLV-I前病毒的gag、env和pX序列,这些婴儿的母亲为HTLV-I血清反应阳性。在22名婴儿中,有5名被发现含有HTLV-I前病毒基因组。通过传统的抗体/抗原检测方法,这5例中的2例不仅抗HTLV-I抗体呈阴性,而且培养淋巴细胞上的病毒抗原也呈阴性。这些结果表明,PCR作为一种简单且高度灵敏的检测HTLV-I感染的方法具有很大用途。
